Abstract: An air pump for inflating an inflatable article includes a multi-stage centrifugal compressing section for inhaling and compressing primary air and a secondary air inhaling mechanism provided downstream of the multi-stage centrifugal compressing section. At the beginning of the inflation operation, extra secondary air can be rapidly inhaled into the air pump and delivered into the inflatable article mainly by means of the secondary air inhaling mechanism and thereafter, when the inner pressure of the inflatable article gradually increases to exceed the predetermined level, the secondary air inhaling mechanism may be closed so that only the multi-stage centrifugal compressing section for primary air functions to continue the subsequent inflation operation in a higher pressure range. Thus, an ideal and speedy inflation operation may be achieved without reducing the inflation pressure.
